If a is a divisor of 12, then

a \in \{-12, -6, -4, -3, -2, -1, 1, 2, 3, 4, 6, 12\}

If 3 is a factor (i.e. divisor) of a, then a can only be one of the elements of this set that are multiples of 3, so

a \in \{-12, -6, -3, 3, 6, 12\}

But a is positive, so there are 3 possible values a can have.

What is negative 0.083 (repeating) as a fraction
Dovator [93]
<span>X= -0.083….. as fraction.
=> x = -0.083…
=> Let 10x = -0.83
Therefore, 10x and x = -8.3… and  -0.083….
Now let’s subtract both number
=> 9x = -7.47 (let’s round off -7.47 to 7.5)
=> 9x = - 7.5 ( fraction of -7.5 = -15/2)
=> 9x = 15/2
=> x = 16/18
=> therefore x= 16/18 or 5/6</span>
